To all whom it may concern:

Be it known that I, THOMAS T. HART, a citizen of the United States, residing at Bradford, in the county of McKean and State of Pennsylvania, have invented certain new and useful Improvements in Coasting-Sleds; and I do hereby'declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention consists in the novel features hereinafter described, reference being had to the accompanying drawing which illustrates one embodiment of my invention selected by me for purposes of illustration, and the said invention is fully disclosed in the. following description and claims.

Referring to the drawings:

Figure 1 represents a side elevation of a coasting sled embodying my invention.

Fig. 2 is a front elevation of the same.

Fig. 3 is a vertical sectional-view somewhat enlarged of portions of the seat post and the braces associated therewith, and

illustrating the manner in which they are connected together.

"Fig. 4 is a horizontal sectional view of Fig. 3 at the line 4% thereof.

Fig. 5 is an enlarged detail View partly in section showing the lower end of one of the lateral braces and its connection with the clamping bolt.

Fig. 6 is an enlarged detail View representing the upper end of one of the lateral brace bars and illustrating a modified form thereof.

Fig. 7 is a section on line 7.7 of Fig. 1.

My invention relates to coasting sleds provided with a single runner, and being of the type commonly known as jumpers. In the embodiment of my invention herein illustrated, and selected by me for purposes of illustration, 1 represents a runner which is composed preferably of channel iron having a central body portion and upturned lateralfianges. This runner is of considerable length and at each end the flanges arecut away to permit the central body portionb'eing bent upwardly and over upon itself to form rounded portions or eyes indicated at 2. The rear portion of the runner, for

example, the portion from a2'y Fig. 1 and j constituting approximately eleven-thirtieths' of the entire length ofthe runner-,is per fectly straight on the'bottomy-From'the ing or welding 'Inanner.

point y forward for a substantially equal distance, as from y 2,-Fig. l, the bottom of the runner curves upwardly a distance approximately equal to one-twenty-fourth of the length of the runner, above a straight line continuous with the bottom of the portion a" y. The remaining forward portion of the runner, from 2 to '10, Fig. 1, and being approximately eight-thirtieths of the length of the runner rises approximately four-thirtieths of the length of the runner above a straight line continuing from the bottom of the portion w y. I find that this construction of runner assures gradual or easy ascent of snow or other obstruction, and packs the snow very gradually as the runner moves over it so that the straight orfiat portion :v-y which forms the main bearing surface slides more easily than would otherwise be the case. v

The runner is provided with a seat which is supported directly above the straight or flat portion w y. I prefer to form a seat supporting post, which is also preferably formed of channel iron and which comprises two vertically disposed portions 3 and 4: bent toward each other to form contacting knees as at 5 and 6, the upper ends of the "bars 3 and 4 being connected by a longitudinally disposed portion, 7, which inclines slightly downward from front to rear. I prefer to form this seat post from a single pieceof channel iron as shown herein; the lateral flanges of the channel iron being cut away at each end of the horizontal portion 7 to permit the bodyportion to bebent as shown, the lateral flanges of the channel iron being disposed as shown and the flanges of the part 7 extending upwardly as indicated at 7. The lower ends of the bars 3 and a of the seat post have their body portions bent horizontally as indicated at 3 and lt and these portions are secured to the runner by bolts and nuts, or by rivets, or bybrazor in any other desired In order to stifien the seat post I prefer to provide a front brace, indicated at 8, extending from the forward portion of the runnerto thepoint where the knees 5 and 6 of the seat post come together. For convenience I prefer to make the seat post of I channel iron slightly narrower than that used for the runner and I make the front brace, 8, of channel, iron slightly narrower than that used for the also prefer to seat post, so that the upper end of the brace, 8, may lie between the lateral flanges of the portion 4 of the seat post as shown, the said upper end having a 'portion indicated at 9 in Fig. 3 which lies against the body portion ber 10 which has an angular-portion adapt ed to engage the exterior face of the knee portion 5 of the post bar 3 and extend a distance above and below the same, the seat clamping member being provided at each side with an eye 11 (see Figs. 1 and 1). I also provide a second clamping member 12 which is constructed to engage an exterior portion of the post bar 4 adjacent to the knee, 6, and extend above the same and also extend over the upturned orbent portion, 9, of the front brace, and for a distance downward therefrom on the body portion of the front brace as clearly shown in Fig. 3. This clamping member is also provided with an eye, 13, on each side. The clamping members may be formed of cast metal or drop forgings as preferred.

The clamping members, 10 and 12, are connected by bolts, 14,"which unite them and clamp them upon. the knee portions of the seat post and the upper end of the front brace, 8, thus uniting all these parts rigidly. The lower end of the front brace is provided with a horizontally disposed portion, 8 which is united to the runner by bolts or rivets or by. welding or brazing as may be preferred. I prefer to extend the foot portion, 8*, of the brace 8 along the upper face of the main body of the runner a considerable distance and preferably to the forward end of the runner, as shown in the drawing in Figs. 1 and 7, so that the foot portion, 8*, reinforces the forward end of the runner in front of the brace '8 and stiflens it so as to prevent the runner from being bent upwardly in case it strikes a stone or other obstruction.

15 represents a seat which is disposed transversely with respect to the runner and is provided on'its under side, centrally, with a pair of kerfs, 16, or grooves to engage the lateral flanges 7 of the top piece, 7 of the seat post, as clearly shown in Fig. 2, thus affording a firm support for the, seat and preventing the seat from moving laterally or twisting with respect to the seat post. may also provide the seat with outwardly extendin pins, 17, adapted to pass through holes in t e body portion of the top piece, 7, of the seat post to prevent the seat from moving longitudinally with respect thereto.

nected to the seat. In Figs. 1 and 2 I have shown the upper ends of the braces, 18, perforated and secured to screw eyes, 20, which are screwed in to-the under side of the seat and in this construction the screw eyes are screwed into the seat before the lower ends of the braces are connected with the bolts 14:. The braces, 18, as will be seen,

unite the seat firmly to the seat post and prevent any rocking of the seat with respect to the post.

I may in some instances connect the upper ends of the braces, 18, detachablyito the seat. For example, in Fig. 6, I have shown a modified form of brace bar indicated at 18,

the upper end of which is provided with a horizontal portion 18 having therein a slot 18 extending transversely" and of such length as topermit the passage of a screw eye therethrough, the screw eye being indi \cated at 21 used, the screw eyes can be inserted in the bottom of the seat at the proper point and the brace bars 18 maybe connected by'simply slipping the slot 18 over the head of Where this constructionis the screw eye and turning the screw eye at right angles tothe slot, and in like manner by turning these screw eyes the brace bars may be disconnected andthe seat lifted off,

the. lateralv braces falling to a vertical po-' sition on each side of the seat post, swinging on the bolts 14 hinge fashion, and this will be found very convenient for packing or storing the device. In the construction shown in Figs. 1 to 5 the seat may be detached by dlSCOIlHGCtlIl the bolts 14 and nuts 14 and removing the bolts, leaving the lateral braces connected with the seat.

In packin the devices for shipment or for storing iem in the house when not in use, the seat will be disconnected and laid flat against the seat post. In packing a quantity of these devices for shipment the eyes or loops 2, 2 at the ends of the runner perform an additional function in that they may be slippedover a pair of rods which will connect any desired number of the de-- having his weight supported ahnost entirely by the straight or flat portion of the nmner, the rider by inclining his body backward or forward or sidewise steers the device in a manner well understood by those by whom 'these devices are used. It will be noticed that there is ample room in front of the post fo the rider, ordinarily a child, to swing his or her legs, thereby helping to maintain balance and to steer the device. Another object of the space immediately in front of the post provided in my improved device is that the rider can grasp the. seat with a hand on each end and holding the jumper in a slanting position behind his back may run until he attains sufficient momentum and then bring the runner into contact with the snow so as to apply the momentum to the sled, thus facilitating the use of the device in sliding even on level portions- It will also be noticed that the seat is inclined slightly backward and is, therefore, more comfortable especially when coasting down inclined surfaces.

In use the device is very readily steered by leaning to one side or the other so as to avoid obstructions and follow a curved ber connecting the upper ends of said standards, the lower ends of said standards being secured to the runner, and a seat supported upon said horizontally disposed mem her.
